Death of a “gentle giant” A popular finalist on the television show MasterChef, Josh Marks is seen working here on one of his culinary masterpieces. In 2013, just a short time after leaving the show, Marks shot himself to death. Affectionately known to viewers as the “gentle giant” because of his 7-foot-2 frame mixed with a mild manner, Marks suffered from both bipolar disorder and schizophrenia—a pair of disorders that contributed to his act of self-destruction.
